Anti-Lock Brake System (Equipped Models)
The yellow ABS indicator (LED) may come on if the en-
gine is run with the motorcycle on its stand and the trans-
mission in gear. If the indicator comes on, just turn the
ignition switch off, then clear service code 42, which indi-
cates a "Faulty front wheel rotation sensor."
When the ABS operates, the ABS makes noise and the
rider feels the reaction force on the brake lever and brake
pedal. This is a normal condition. It informs the rider that
the ABS is operating normally.
Service codes detected once by the ABS hydraulic unit
will be memorized in the ABS hydraulic unit. Therefore,
after maintenance work is finished, be sure to erase the
service codes. Do not erase the service codes during
troubleshooting. Wait until all the checks and repair work
are finished to prevent duplication of previous service
codes and unnecessary maintenance work.
Before delivering the motorcycle to the customer, be
sure to erase any service codes which might be stored in
the ABS hydraulic unit. Using the self-diagnosis feature,
make sure that the yellow ABS indicator (LED) lights.
A fully charged battery is a must for conducting reliable
self-diagnosis. Test run the motorcycle at a speed of
more than 20 km/h (12 mph) to see that the yellow ABS
indicator (LED) does not come on. Finally, test run the
motorcycle at a speed of more than 30 km/h (20 mph)
and brake suddenly to see that the motorcycle stops
without loss of steering control and the ABS operates
normally (The reaction force generated is felt in the brake
lever and pedal.). This completes the final inspection.
ABS Troubleshooting Outline
When an abnormality in the system occurs, the yellow
ABS indicator (LED) lights up to alert the rider. In addition,
the nature of the fault is stored in the memory of the ABS
hydraulic unit and when in the self-diagnosis mode, the ser-
vice code [A] is indicated by the number of times the yellow
ABS indicator (LED) blinks. The service codes stored in
memory are not erased until the mode has been changed
to the fault erase mode after the fault has been corrected.
Therefore, after correcting the problem, always erase the
service codes and then run the self-diagnosis program to
confirm normal signal output. When, due to a malfunction,
the yellow ABS indicator (LED) remains lit, get a thorough
understanding of the background before starting the repair
work. Ask the rider about the conditions [B] under which
the problem occurred and try to determine the cause [C].
Do not rely solely on the ABS self-diagnosis function, use
common sense; check the brakes for proper braking power,
and brake fluid level, search for leaks, etc.
